Abstract:

The stability of esmolol hydrochloride in a variety of i.v. solutions was studied. Solutions of esmolol hydrochloride 10 mg/mL were prepared separately in 0.45% sodium chloride injection, 0.9% sodium chloride injection, 5% dextrose injection, 5% dextrose and 0.45% sodium chloride injection, 5% dextrose and 0.9% sodium chloride injection, 5% dextrose with lactated Ringer's injection, lactated Ringer's injection, 5% sodium bicarbonate injection, and 5% dextrose injection with potassium chloride 40 meq/L. One glass and one polyvinyl chloride container of each solution (except glass only in the case of the solution in 5% sodium bicarbonate injection) were stored in the dark at 5 degrees C, under ambient room light at 23-27 degrees C, in the dark at 40 degrees C, and under intense light at 25-30 degrees C. At storage intervals up to 168 hours, samples were tested for esmolol hydrochloride concentration by high-performance liquid chromatography. Optical density and pH were also measured. Esmolol hydrochloride was stable in the various i.v. fluids for at least 168 hours when stored at 5 degrees C or 23-27 degrees C, for at least 24 hours when stored under intense light, and, with one exception, for at least 48 hours when stored at 40 degrees C. When mixed with 5% sodium bicarbonate injection, the drug was stable for only about 24 hours at 40 degrees C. There were no substantial changes in optical density or pH. The type of container had no effect on stability. With one exception, esmolol hydrochloride was stable in all the i.v. solutions under all the conditions tested.
